Blogging With AI (ChatGPT)
February 23rd, 2023 | 
Author: Sorry that I have not been posting much on my blog. I have several other projects consuming my time and this blog has been neglected.
Then, it hit me: I should just let ChatGPT, a free artificial intelligence (AI) platform that is getting a lot of attention, write my blog for me. All the Cool Kids are Using It. I just entered “Please write my next blog post about VHF ham radio” and this is what I got back:
VHF Ham Radio: Exploring the World Above 50 MHz
When most people think of ham radio, they usually picture a person sitting in a dark room, talking into a large radio with a huge antenna. However, ham radio can be much more than that, especially when you start exploring the VHF bands.
VHF, or Very High Frequency, refers to the portion of the radio spectrum between 30 and 300 MHz. This includes the 6-meter (50 MHz), 2-meter (144 MHz), and 70-centimeter (440 MHz) bands, which are commonly used by amateur radio operators for local and regional communication.
One of the main advantages of VHF ham radio is that it allows for much greater range than the traditional HF bands (below 30 MHz). This is because VHF signals travel mostly in a straight line, and are less affected by the ionosphere and other atmospheric conditions that can impact HF propagation.
In addition to traditional voice communication, VHF ham radio operators also use a variety of digital modes such as Packet Radio, APRS, and D-STAR, which allow for the exchange of data and information over the airwaves.
Another popular VHF activity is contesting, which involves making as many contacts as possible in a short period of time. Contesting can be a fun and exciting way to improve your operating skills and test your equipment.
VHF ham radio is also a great way to get involved in emergency communication and public service. Many amateur radio clubs and organizations work closely with local authorities to provide communication support during emergencies and events.
If you’re interested in exploring the world of VHF ham radio, there are a few things you’ll need. First, you’ll need a radio that covers the VHF bands. There are many options available, from handheld transceivers to base stations with large antennas.
You’ll also need an antenna that is specifically designed for VHF operation. These antennas are typically shorter and more compact than HF antennas, and are available in a variety of types and configurations.
Finally, you’ll need to obtain a ham radio license from the FCC. The process is relatively straightforward and involves passing a written exam that covers basic radio theory, regulations, and operating procedures.
In conclusion, VHF ham radio offers a world of opportunities for communication, experimentation, and public service. Whether you’re a seasoned operator or a newcomer to the hobby, there’s always something new to discover on the VHF bands.

Most Active SOTA Summits in Colorado
Previously, I wrote that Mount Herman (W0C/FR-063) is the most radio-active summit in Colorado. Here is a fresh look at the data, with seven Colorado SOTA summits that have at least 100 activations. The W0C page on sotl.as is quite handy for viewing this information. Mount Herman still leads the pack by a wide margin, with many activations by Steve/WG0AT.
Pikes Peak is still in second place but Genesee Mountain is essentially tied with it. Pikes Peak is a 14er but has a road to the top and most of those activations are probably aided by a vehicle. Genesee is a much lower, easy-to-access summit just west of Denver. Chief Mountain has edged out Mt Evans for fourth place.
The summit formerly known as Squaw Mountain has been renamed Mestaa’ehehe Mountain (W0C/PR-082). There is a gated road to the top so most activators hike that road.
Thorodin Mountain made the list as it seems to be gaining in popularity, with Carey/KX0R as a frequent activator.
Most of these summits are in the Front Range section of W0C, close to the major cities which aids their popularity. The other two are listed in the Park Range and the Sawatch Range, but they are also not far from the large urban areas.
First in North America
In North America, Mount Herman is second to Mount Davidson (W6/NC-423) which currently has 522 activations, many of them by Ellliot/K6EL. Davidson is a small summit in the middle of San Francisco, so it has easy access for a large population. This video by W6DFM provides a tour of that summit.
So that’s your update on SOTA activations in Colorado.

Top Five K0NR Blog Posts for 2022
Closing out 2022, here are the top five blog posts at k0nr.com during the year. Some people may see this as a lazy way of creating one more blog post for the year without much effort and they would be right.
Top Five Blog Posts
Leading the list is this blog post…a perennial favorite that seems to make the top five each year. This particular article is tuned for Colorado but it also provides a link to an article that covers the topic for the USA.
This is another popular article that provides an introduction to 2m SSB operating.
In third place, this post explains how the FCC rules get in the way of having one radio that does everything.
This older April Fools article from 2019 jumped into fourth place this year. I am not sure why it suddenly popped onto the scene but I think it is a fun article as long as you don’t take it seriously.
In fifth place is one of my favorites, an article that encourages hams to “make some noise on 2m FM.”
Editors Choice
Just for good measure, I am including one more post that I think is notable. This one promotes the idea of the North America Adventure Frequency (146.58 MHz), which is working out nicely.
Also, take a look at this post:
Merry Christmas and Happy New Year!

Microphone Hanger for Backpacks
My standard SOTA setup is a Yaesu FT-90 compact VHF/UHF transceiver stuffed into a fanny pack with its Bioenno battery pack. The fanny pack is a pretty nice flyfishing pack that I position on the front side of me so I can easily see and operate the radio. I am usually holding the 2m or 70 cm Yagi antenna and talking on the microphone.
I’ve been looking for a way to clip the microphone onto the pack. Typically, what happens now is I drop the microphone and it gets banged up when it hits the rocky ground. I needed a way to easily hang it on the side of the pack. I recalled having an old cellphone belt clip that accepts the standard button on the back of a mobile microphone, but I couldn’t locate it. However, I did find one on Amazon.
I clipped it onto my fanny pack and the Yaesu microphone hangs quite nicely on it. This clip can be used for other applications…anywhere you want to hang a microphone onto a backpack, belt, or whatever. Depending on your station configuration, this may be useful for all kinds of portable operating: SOTA, POTA, and satellites.

Who Does VHF SOTA?
Who really uses the VHF and higher bands (>50 MHz) for Summits On The Air? Last year, I pulled some data from the SOTA database and provided some analysis.
Here is the short story:
Roughly 20% of the SOTA contacts worldwide are on VHF/UHF frequencies and about 90% of these are on 2m FM.
So that’s the information that is in the official SOTA database. For SOTA, I pretty much operate on the VHF/UHF bands so over time I’ve noticed that four types of operators use VHF/UHF for SOTA. Of course, this is based on my own observations, mostly in Colorado but also in other states.
Beginners
Many newer hams or new-to-SOTA hams just grab their handheld radio and go do a SOTA activation. This makes a lot of sense, assuming there is reasonable 2m FM simplex activity around. Summits that are within VHF range of large population areas usually work quite well. A Technician license is sufficient to have fun with this mode (both activating and chasing). If you are new to ham radio, like the outdoors, and have SOTA summits in your area, this is a fun activity to pursue!
HF+VHF Ops
Many SOTA activators are after longer distance contacts so they naturally gravitate to the HF bands. Some leave VHF behind, as they focus on HF operating. However, many SOTA activators and chasers keep a VHF radio in their toolkit, often treating it as an add-on to their HF activity. Sometimes the VHF radio becomes the fail-safe mode if things are not working well on the HF bands. Sometimes, I hear activators say something like “the HF gear was just not working for me today, so I had to use my HT to log four contacts.”
Non-SOTA Ops
There are quite a few hams out there on 2m FM that are not really focused on SOTA. They like to hang out on 2m FM simplex, especially 146.52 MHz, to chat with whoever comes along. In the backcountry, this may include hikers, snowshoers, skiers, 4WD enthusiasts, campers, etc. It also includes hams just hanging around the shack with a radio or scanner monitoring 2m FM. Announce that you are on top of a summit and these folks are happy to contact you.
VHF Enthusiasts
Finally, there are VHF/UHF enthusiasts that like the combination of higher frequencies and mountaintop operating. The effect of Height Above Average Terrain (HAAT) has a huge impact at these frequencies. A 5-watt handheld (HT) might be limited to a few miles on flat terrain, but from the top of a summit, the range extends dramatically (50 to 100 miles). Improve your station and 200-to-300-mile contacts are achievable. Most of this action is still on 2m FM but adding in additional bands (70 cm, 23 cm) and modes (CW, SSB) provides another challenge. Chasers are included in this category as well…there are VHF/UHF enthusiasts that are challenged by working distant summits from home.
Summary
These are the four categories of folks I usually encounter on the VHF/UHF bands when doing SOTA. Do these match your experience? What did I miss?
